25. Members
Surgeon
heads surgical team
Makes decisions related to surgical procedure
May need assistant
Surgical assistant (other doctor, surgical tech, resident, intern)
May hold retractors, suction wound, cut tissue, suture, and dress wounds depending on scope of practice and under supervision of physician
Anesthesia
Anesthesiologist or Certified Registered Nurse Anesthestist
Maintains airway
Monitoring circulation/respiratory status
Replace blood/fluid loss

26. OR nurses Holding area nurse Primary role is Circulating Nurse
Duties performed outside of sterile field
Scrub Nurse
Passes instruments, sponges in the sterile field
Perform surgical scrub
Very specialized role, most education is during orientation, not in nursing school.

27. Surgical Areas Operating Room Restricted area
Trend towards less invasive procedures (less scarring, quicker recovery, decreased length of hospitalization

28. Basic Guidelines for Surgical Asepsis
All materials in contact with the wound and within the sterile field must be sterile.
Gowns are sterile in the front from chest to the level of the sterile field, and sleeves from 2 inches above the elbow to the cuff.
Only the top of a draped table is considered sterile.
Items are dispensed by strategically to maintain sterility.
Movements of the surgical team are from sterile to sterile and from unsterile to sterile only.

29. Movement around the sterile field must not cause contamination of the field. At least a 1-foot distance from the sterile field must be maintained.
Whenever a sterile barrier is breached, the area is considered contaminated.
Every sterile field is constantly maintained and monitored. Items of doubtful sterility are considered unsterile.
Sterile fields are prepared as close as possible to time of use.

31. Question
true or false.
To maintain surgical asepsis, the nurse knows that the sides and top of a draped table is considered sterile.

32. Answer
False.
Rationale: Sterile drapes are used to create a sterile field. Only the top surface of a draped table is considered sterile. During draping of a table or patient, the sterile drape is held well above the surface to be covered and is positioned from front to back.

33. Infection
Anyone with open wound, cold, or any infection should not participate in surgery
Jewelry should be minimal
Hands of surgical staff are usually cultured every 3-6 months to determine possible nosocomial (hospital acquired) infections

35. Attire

36. Time out procedure
Nurse asks pt to confirm procedure and is verified with consent form
Patient verifies the right site and surgeon
2 patient identifiers
Site mark
“Time out”
Name, procedure, site, document
See pg. 612

37. Anesthesia

38. Anesthesia
Def: induced state of partial or total loss of sensation, occurring with or without loss of consciousness.
Purpose: block nerve impulse transmission, suppress reflexes, promote muscle relaxation, and sometimes achieve controlled level of unconsciousness
Choice depends on: type and duration of procedure, area of body, safety issues, emergency, pain management after surgery, last meal or liquids or drugs

39. Types General—see slides Local- Novocaine for example Hypnosis
Cryothermia
Acupuncture
TABLE ON PAGES

40. General
Definition: reversible loss of consciousness induced by inhibiting neuronal impulses in several areas of the central nervous system
Depress CNS
Results in analgesia (pain relief), amnesia (memory loss), and unconsciousness with loss of muscle tone and reflexes
Used in head, neck, upper torso and abd surgeries

41. Stages of general 1:sedation administered
Induction and LOC, decreased sensation
Warmth, dizziness, noises exaggerated
2: excitement/delirium
LOC and relaxation, regular breathing
Pupils dilate, HR increases, may need to restrain pt
Do not touch pt
3: operative anesthesia
Muscle relaxation, depressed vitals
Unconscious, maintained for hours
4:danger = Medullary Depression
Depressed vs, respiratory failure
Too much anesthesia, cyanosis
Emergence: recovery from anesthesia

42. Types of general Inhalation: most controllable Fast acting
Passes through vaporizer
Depresses CNS
Ex: Nitrous Oxide

43. Induce and maintain anesthesia Anesthetics Opiods
IV: rapid and pleasant
Induce and maintain anesthesia
Anesthetics Opiods
Etomidate Fentanyl
Valium Morphine
Versed
Diprivan
Reversal agent for opoids=Narcan (0.2mg)
Reversal agent for Benzos = Romazicon(0.2mg)

44. Muscle relaxants Affect skeletal muscle Administered before intubation
Assess with nerve stimulator
Succinylcholine, Tracrium, Vecronium
Reversal agent= Neostigmine (0.5-2mg

45. Balanced: minimal disturbance to function, used with elderly and high risk
Regional (Spinal, Epidural, Peripheral nerve block)~ gag and cough stay intact
block transmission of sensory impulses
Does not depress respirations
Local injection of med

46. Types of Regional Anesthesia
Spinal
Local anesthetic injected into subarachoid space, directly into CSF
“Blocks” at level of spinal cord (sensory and motor)
Epidural
Local anesthetic into epidural space
Peripheral nerve block
Anesthesia of a certain area
No systemic effect

47. Complications of RegionalHA

49. Malignant Hyperthermia
Life threatening
Predisposition is genetic

50. causes increased calcium and potassium levels in skeletal muscles
Immediate reaction or several hours later
s/s: tachycardia, dysrhythmias, muscle rigidity (jaw, face), hypotension, tachypnea, mottling, cyanosis, myoglobournia (muscle proteins in urine),
*increase in CO2 and decrease sat
Care: stop agent, intubate, give dantrium to reverse, check ABG, cooling techniques, monitor core temp, EKGs, insert foley, hydrate, ICU for at least 24 hours
Chart 26-3

51. Manifestations Hypoxia Hyperthermia****THIS IS A LATE SIGN****
Dysrhythmias
Hypotension
Early signs:
contracture of jaw
Sinus tach
Increase in expiratory CO *Pg. 630 *

52. Complications continued
Overdose: can occur if metabolism and drug elimination are slower (ht, wt, and allergies are vital to know before administration)
Unrecognized hypoventilation: failure to exchange gases can lead to cardiac arrest, permanent brain damage, and death. Vital to use end tidal carbon dioxide monitor to confirm the exchange

53. Intubation complication
Broken or chipped teeth
Swollen lip
Vocal cord trauma

54. Question
Malignant hyperthermia usually manifests within what time frame after induction of anesthesia?
5 minutes
10–20 minutes
30 minutes
45 minutes

55. Answer
10–20 minutes
Rationale: Malignant hyperthermia usually manifests about 10 to 20 minutes after induction of anesthesia. It can also occur during the first 24 hours after surgery.

56. Local Numbing agent is used Mentally alert
Complications: potential cardiac depression, toxic reaction, edema, blurred vision, inflammation, etc. see

57. Types of local Topical Infiltration: directly into wound or lesion
Blocks:
Field: injections around work site (lidocaine, novocaine)
Nerve: injection into or around nerve in involved area-used for chronic pain relief
Spinal: injection of agent into CSF in the subarachnoid space-absorbed rapidly
Epidural: placed in epidural space-may affect breathing

60. Moderate (Conscious) Sedation
Minimally depressed LOC
Pt able to maintain airway
Pt responds to physical and verbal stimuli

61. Moderate (Conscious) Sedation
As a nurse, what do you need to have available at the bedside?
What medications might be given?
What monitoring/assessments?
What types of procedures?

62. Potential Adverse Effects of Surgery and Anesthesia
Allergic reactions or drug toxicity
Cardiac dysrhythmias
Over sedation or Under sedation
Trauma: laryngeal, oral, nerve, and skin, including burns
Hypotension
Thrombosis
See Chart 19-1

63. Gerontologic Considerations
Elderly patients are at increased risk for complications because of:
Pre-existing conditions.
Aging heart and pulmonary systems.
Decreased homeostatic mechanisms.
Changes in responses to drugs because of changes such as decreased renal function, etc.

64. Nursing diagnosis Risk for injury r/t positioning
Impaired skin integrity r/t surgical incision
Risk for infection

65. Important to remember
Always know client’s wishes about life sustaining measures because they apply in the OR as well
However some facilities/doctors require that the surgical client that is DNR on unit is full code in OR.
Always know the allergies and reactions
Always know current lab values because they could postpone surgery
Know the client’ s baseline vitals to monitor for complications
Patient identification
Correct informed consent
Verification of records of health history and exam
Safety measures such as grounding of equipment, restraints, and not leaving a sedated patient
Verification and accessibility of blood

66. Positioning Accommodates access Surgical view

SUCCESS IN MANY CASES

69. Antiobesity drugs:
Orlistat (approved Feb ’07)
- reduces absorption of fat by inhibiting pancreatic lipase
Metformin
Byetta (delays gastric emptying)

70. Bariatric Surgery Roux en Y: most commonly performed
- least likely to result in nutritional
deficiencies
- small bowel is divided & arranged
into a “y” and attached to the small
stomach pouch
- pt feels fullness rapidly after eating

71. Post op
Starts at the completion of surgery and transfer to PACU or ICU
Stabilize VS, maintain airway
Prepare pt for discharge

Renal
Output, urine retention is common if no foley Gi
N/V, peristalsis, monitor for ileus, NG tube output if indicated
Skin
Monitor wound, drainage, drains, dressings,
Vitals are vital
Usually q15” x4, q30” x4, q1hr x4, q2hr x4, then q4hr
Respiratory status
Airway management, lung sounds, muscle use, snoring, stridor (high pitched crowing)
Monitor PAIN

73. Early infection can be indicated on increase in band cells of the WBC differential (left shift)
Get culture
Notify MD
Monitor ABGs and CMP

75. Aldrete Post Anesthesia Recovery Score (PARS)
Numerical scoring system to eval PACU patients
Based on activity, Respirations, Circulation, Consciousness, O2 Sats
Ranges from 0 to 10, 10 is the best
Score when arrives in PACU, every 30 min until 8 or higher is achieved
Score also done at discharge

76. Nursing diagnosis

77. Impaired Gas Exchange Open airway

79. Risk for Decreased Cardiac Output
Rhythm, cardiac output
BP, heart rate consistent with baseline
Monitor for sinus tachycardia/bradycardia, identify and treat cause
Monitor for hypotension; IV fluids, patient positioning
Monitor for hypertension, identify and treat cause

80. Risk for Imbalanced Body Temperature: Hypothermia
Normal core temperature
Monitor for core temperature <36°C (96.8°F), shivering, patient report of feeling cold
Risk factors: patient history, length of surgery, cold solutions
Blankets, clothing, ambient temp
Treat with active warming, meds

81. Pain Physiological and psychological effects
Delayed ambulation, diminished functioning
Monitor for pain management and respiratory depression
PCA, PCEA: monitor for pain relief, untoward effects
Monitor sensory level of the epidural
